Many applications when run in Windows 7 change the application's taskbar alerts to indicate changed state - but once you've clicked the window, they return to normal. The primary place I see this is Windows Live Messenger - when you receive a message, a little speech bubble appears on the taskbar icon; once you've clicked the window with the message, the speech bubble disappears.
However, I'm pretty keyboard oriented. And alt-tabbing to the chat window doesn't seem to be sufficient to tell the system to stop telling me.
Is there any way to fix this? Because I haven't got any other applications that make much use of the functionality, I'm unclear on whether it's the fault of Windows or Messenger...
